Basically unpack the contents into 
C:\Documents and Settings\Solitude\My Documents\My Games\Unreal Tournament 3\UTGame\Published\CookedPC\CustomMaps

and run the game. 

I like the concept of low visability and a maze layout to help level the playing field and make the gameplay exciting. For this level, i kept the LOD low with no powerup items..basically fight till you can fight no more. Also becuase of scale,this level works best with as many players as possible so max out bot settings for the best results...the more the merrier. Vehicles may not work in team deathmatchs...Last thing...If you respawn in an area and you are not sure how to manuever out....LOOK UP!
ENJOY!
